– CodeDeployで、service httpd stop, service httpd startの処理を入れる

### shellの作成
@local

scripts/stop_server

#!/bin/bash
isExistApp = `pgrep httpd`
if [[ -n $isExistApp ]]; then
	service httpd stop
fi

scripts/setpermission.sh

#!/bin/bash
chmod -R 777 /home/release/storage

scripts/start_server

#!/bin/bash
service httpd start

appspec.yml

version: 0.0
os: linux
files:
  - source: /
    destination: /home/release
hooks:
  ApplicationStop:
    - location: scripts/stop_server
      timout: 300
      runas: root
  AfterInstall:
    - location: scripts/setpermission.sh
      timeout: 300
      runas: root
  ApplicationStart:
    - location: scripts/start_server
      timout: 300
      runas: root

$ git add .
$ git commit -m “appspec.yml update”
$ git push -u origin master

# ec2 -> instance -> start
$ ssh ec2-user@${public_ip} -i ~/.ssh/***.pem
$ cd /home/release
$ ls
LICENSE appspec.yml index.html
// httpd serverをインストール
$ sudo yum update
$ sudo yum install httpd
$ sudo systemctl start httpd
$ sudo systemctl status httpd
$ sudo systemctl enable httpd
$ sudo systemctl is-enabled httpd

# CodeDeploy -> Applications -> create deployment -> commit idを入力
$ ls
LICENSE appspec.yml index.html scripts

なるほど、appspec.ymlの公式を確認します。
hooksのフローはこちらに掲載されています。
https://docs.aws.amazon.com/ja_jp/codedeploy/latest/userguide/reference-appspec-file-structure-hooks.html

BeforeInstall – 置き換えタスクセットが作成される前にタスクを実行
AfterInstall – 置き換えタスクセットが作成され、ターゲットグループの 1 つがそれに関連付けられた後、タスクを実行

Git pushするとCodeDeployでEC2にDeployされる方法

##　IAMユーザの作成
Add user: GitHub
Access type: Programmatic access
Policty: AWSCodeDeployFullAccess
Permission: CreatePolicy

Policy Name: CodeDeploy-Access

Json

{
    "Version": "2020-03-07",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "codedeploy:GetDeploymentConfig",
            "Resource": "arn:aws:codedeploy:ap-northeast-1:${account id}:deploymentconfig:*"
        },
        {
            "Effect": "Allow",
            "Action": "codedeploy:RegisterApplicationRevision",
            "Resource": "arn:aws:codedeploy:ap-northeast-1:${account id}:application:${application name}"
        },
        {
            "Effect": "Allow",
            "Action": "codedeploy:GetApplicationRevision",
            "Resource": "arn:aws:codedeploy:ap-northeast-1:${account id}:application:${application name}"
        },
        {
            "Effect": "Allow",
            "Action": "codedeploy:CreateDeployment",
            "Resource": "arn:aws:codedeploy:ap-northeast-1:${account id}:deploymentgroup:${application name}/${deploy_group}"
        },
        ]
}

### GithubでCodeDeploy用のサービスを追加
– Deploy対象のレポジトリに移動
-> Settings->Integration & Services

Note: GitHub Services have been deprecated. Please contact your integrator for more information on how to migrate or replace a service with webhooks or GitHub Apps.

Servicesは終了しているので、現在はできないようです。

## 準備
### 1. IAMロール作成
– CodeDeploy
— Name: CodeDeploy
— Policy: CodeDeployRole
– ec2
— Name: s3readonly
— Policy: AmazonS3ReadOnlyAccess

### 2.VPC作成
– VPC, public subnet, InternetGateway, RouteTable作成
– SecurityGroup作成

## EC2
### 3.インスタンス作成
– Configure Instance DetailsのIAM roleで上記で作成したs3readonlyのroleを選択する
– VPC, public subnet, InternetGateway, RouteTable, SecurityGroupも作成したもの選択する
– SSHログイン

$ ssh ec2-user@****** -i  ~/.ssh/***.pem

### 4.EC2にCodeDeployAgentのインストール
$ sudo yum update
$ sudo yum install ruby
$ sudo yum install aws-cli
$ cd /home/ec2-user
$ aws s3 cp s3://aws-codedeploy-ap-northeast-1/latest/install . –region ap-northeast-1
$ chmod +x ./install
$ sudo ./install auto
$ sudo service codedeploy-agent status
The AWS CodeDeploy agent is running as PID 12399

## 5.Github repository
${repo_name}/appspec.yml

version: 0.0
os: linux
files:
  - source: /
    destination: /home/release

### 6.CodeDeployのapplication作成
– ServicesのCodeDeployからCreate Application
— test

### 7. Deployment group
– Create deployment group押下
Deployment group name: testDeploy
Service role: codeDeploy
Deployment type: In place
Environment configuration: Amazon EC2 instances
->key:test
Deployment settings: CodeDeployDefault.AllAtOnce

### 8.Create deployment
Deployment group: testDeply
Revision type: My application is stored in Github
GitHub token name: Githubのname
Repository name: ${githubname}/${repository name}
Commit ID: GithubのcommitのID

$ pwd
/home/release
$ ls
LICENSE appspec.yml index.html
